Abstract：
Building wall preparation of phase change material and thermal insulation material, not only can reduce heating energy consumption, but also can reduce indoor temperature fluctuations. Based on the research situation at home and abroad, the composite phase change materials building wall heat transfer process was research by using FLUENT software. The physical parameters and solidification process were analyzed. Numerical simulation results and test measurements were compared. The influence of phase change material volume and phase change wall plate position on the temperature change of the inner wall is obtained. The results show that: when the fly ash composite phase change wallboard thickness was 6 mm and built-in phase change wallboard, heat preservation effect was best.
